WARNING:
Keep away from parts which
rotate; the fan blades can appear invisible
when the fan is rotating.
DO NOT pull or pry on the fan blades. This
practice will cause fan failure. Use only
approved methods and tools for manually
rotating the engine.
WARNING:
DO NOT remove the
radiator cap while the engine and coolant are
hot. Hot coolant under pressure is dangerous
and can injure the eyes and cause severe
burns.
• Cooling system corrosion inhibitors
contain alkali (chemicals that break
down organic substances such as skin
and eye tissue), DO NOT swallow.
Avoid prolonged or repeated contact
with corrosion inhibitors. In case of skin
contact, immediately wash affected
area with soap and water. In case of
contact with eyes, immediately flood
eyes with large amounts of water for a
minimum of 15 minutes. Obtain
medical assistance immediately. Keep
corrosion inhibitors out of the reach of
children.
• DO NOT use salt water or other
corrosive liquid in the cooling system.
WARNING:
Keep sparks and fires away
from batteries. Batteries produce hydrogen
gas, which can explode and cause severe
personal injury and property damage.
Battery fluid can burn the skin and injure the
eyes. If you come in contact with battery acid,
flush the affected area with large amounts of
water and obtain medical assistance
immediately.
WARNING:
Engine oil can cause skin
disorders and other personal injury. Avoid
prolonged or repeated contact with both new
and used engine oil.
WARNING:
Diesel fuel can cause skin
irritation. Use gloves or protective hand lotion
when working on the fuel system.
WARNING:
Before beginning any
adjustments or repairs, place accident
prevention tags in the operator’s compartment
and on the controls, and disconnect the battery
negative cable.
• DO NOT operate, clean, lubricate or
adjust the engine without proper
training.
• NEVER attempt to perform an
adjustment or repair that is not
understood.
• Before servicing, relieve pressure in
fuel, oil, coolant and hydraulic lines.
Obtain medical assistance immediately
if a high-pressure jet of fuel, oil, coolant
or hydraulic fluid strikes the skin.
• DO NOT permit loose clothing, hair,
etc., near moving parts.
• Keep away from parts which rotate; fan
blades can appear invisible when the
fan is rotating.
• To help prevent burns, avoid contact
with components that remain hot after
power is turned off or disconnected.
WARNING:
When replacement is
necessary, ALWAYS use factory-approved
fasteners and parts.
